Cation‐Directed Host–Guest Assembly and Reversible Wheel to Cluster Interconversion in a 20‐Molybdate System

Chemistry – A European Journal, Volume 32, Issue 33, 1 September 2026.
The polyoxo‐20‐molybdate(VI) wheel [MoVI20O60{AsO2(CH3)2}12]12− (Mo20) can be prepared with or without a central guest in a controlled, cation‐directed fashion. When Mo20 is dissolved in water, it exhibits an immediate, quantitative, and fully reversible solution transformation to a tetranuclear Mo4 cluster, which transforms in the solid state again to

Enhanced Tantalum Superconducting Resonator Performance via All‐Surface Organic Monolayer Passivation

Advanced Functional Materials, Volume 36, Issue 64, 10 August 2026.
The internal quality factor of tantalum superconducting resonators is significantly increased by ∼140% in the low photon regime by passivating their surfaces with a high‐quality alkene self‐assembled monolayer. Our methodology promises to enhance the performance of superconducting quantum circuits.

Durable Physically Mixed Microporous and Mesoporous MOFs/Nanofiber Aerogel 3D Composites for Effective Toxic Gas Capture and Organophosphonate Detoxification

Advanced Functional Materials, Volume 36, Issue 13, 12 February 2026.
Ultralight 3D nanofibrous aerogels embedded with metal‐organic frameworks effectively capture and neutralize toxic gases and organophosphonates. Incorporating mesoporous UiO‐66‐NH2 and HKUST‐1 into PAN/PVP fibers enables high MOF loading while maintaining mechanical strength and structural stability.

Novel Human Butyrylcholinesterase Variants: Toward Organophosphonate Detoxication [PDF]

Biochemistry, 2014
Human butyrylcholinesterase (hBChE) is currently being developed as a detoxication enzyme for stoichiometric binding and/or catalytic hydrolysis of organophosphates. Herein, we describe the use of a molecular evolution method to develop novel hBChE variants with increased resistance to stereochemically defined nerve agent model compounds of soman ...

Lanthanide Coordination Networks Based on Diamantane‐4,9‐Diphosphonic Acid

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.
The combination of Ln3+ ions and the diamantane‐4,9‐bis(hydrogenphosphonate) linker results in 3D networks where Eu3+, Gd3+, and Er3+ exhibit an uncommon coordination number of 6. Four new Ln‐based (Ln = Eu, Gd, Er) coordination networks, {[EuL1.5(H2O)4]·H2O}n and {[LnL1.5(H2O)]·H2O}n (Ln = Eu, Gd, Er), were synthesized using the precursor diamantane‐4,

Synthesis of Diaryl‐ and Dialkynylphosphinates From Ubiquitous PV Sources via a Redox‐Neutral Approach

Advanced Science, Volume 12, Issue 36, September 25, 2025.
Classical strategies for P─C bond formation rely on precursors (e.g., PH3, H2PO2, PCl3) obtained from P4, which is produced via the energy‐intensive thermal process. Here, an alternative, redox‐neutral approach is explored. Primary phosphate sources are activated with triflic anhydride (Tf2O) and 4‐dimethylaminopyridine (DMAP) to a versatile PV ...
